A range input (AKA slider) will fall back to a plain text input if it's not supported.
You can use freqdec's Input Range Polyfill or for just Firefox support, Frank Yan's html5slider.
These polyfills aren't drop-in polyfills, and you'll need to wire them up a little, but your markup can depend on <input type=range> creating a slider.
